These achievements laid the groundwork for his most significant contribution: the cellular phone. The Birth of a Revolution. In , Cooper made history by placing the first public call from a handheld cellular phone on the streets of New York City. The phone itself, nicknamed the DynaTAC X, was a far cry from the sleek smartphones we know today.

It weighed a hefty 2. However, it represented a giant leap forward in mobile communication, freeing users from the confines of car phones and bulky briefcase models. Beyond the Invention. He also played a crucial role in developing the cellular network infrastructure that made widespread mobile phone use possible. He worked out the problem in front of them using a chalkboard.

This understanding evolved from the marketplace for two-way radios. However, only three months passed from the time he conceived of a portable phone and until the portable phone was demonstrated. In , a Bell engineer, Doug Ring, and his boss, Rae Young, wrote a memo describing cellular technology. This first mobile telephony service was terrible.

During the interview, Martin Cooper explains cellular technology. He said that a cell is a base station connected to other base stations and to the pubic switched network. When a user moves from one cell to another, the call is transferred from one radio channel to another. The actual switching logic was developed by Amos Joel at Bell Labs.

Their cell phone service market consisted of about two million car phones, an elite service only a few people would want. In November , he called Rudy Krolopp, who had designed the first national pagers. Martin described his idea and said that he wanted for the April demonstration. Two weeks after Rudy Krolopp assigned his team to design the phone, Martin Cooper took them out to dinner.

The team presented their handmade models. These were a flip phone, a slider phone, a lozenge phone and the other one looked like a shoe. By March , the team had a working phone. The Martin Cooper cell phone had to make and receive calls to and from other phones. Martin Cooper born December 26, is an American engineer. He is a pioneer in the wireless communications industry, especially in radio spectrum management , with eleven patents in the field.

On April 3, , he placed the first public call from a handheld portable cell phone while working at Motorola , from a Manhattan sidewalk to his counterpart at competitor Bell Labs. Cooper also sits on committees supporting the U. In , Cooper was elected a member of the National Academy of Engineering for leadership in the creation and deployment of the cellular portable hand-held telephone.

Cooper was born in Chicago to Ukrainian Jewish immigrants. In , he earned his master's degree from IIT in electrical engineering and in received an honorary doctorate degree from IIT. He serves on the university's board of trustees. Schaumburg, Illinois as a senior development engineer in the mobile equipment group. He developed products including the first cellular-like portable handheld police radio system, produced for the Chicago police department in By the early s, Cooper headed Motorola's communications systems division.

Cooper is the lead inventor named on "radio telephone system" filed on October 17, , with the U. Patent Office and later issued as U. Patent 3,, On April 3, , Cooper and Mitchell demonstrated two working phones to the media and to passers-by prior to walking into a scheduled press conference at the New York City Hilton in midtown Manhattan.

Joel S. I'm calling you from a cell phone, a real handheld portable cell phone. That first cell phone began a fundamental technology and communications market shift to making phone calls to a person instead of to a place. Cooper worked at Motorola for 29 years; building and managing both its paging and cellular businesses. He also led the creation of trunked mobile radio, quartz crystal oscillators , liquid crystal displays , piezo-electric components, Motorola A.

Rose to fix a flaw in quartz crystals used in Motorola's radios which encouraged the company to mass-produce the first crystals used in wrist watches. Cooper and his wife Arlene Harris founded Dyna LLC in as a home base for their developmental and support activities for the new companies, Subscriber Computing Inc. He serves on industry, civic and national governmental groups including the U.

In Cooper co-founded Cellular Payphone Inc. Later, at an early age of 9, Martin conceived the idea to improve the trains travelling far north to down south. He had just learnt about friction, so he knew it was necessary to get rid of it. This was just part of it. He further analysed that as air created friction, he had to get rid of it too.

So, the train would have to be in an air tight vacuum tunnel. I mean to think of such a complex idea at that age, totally beats me. Martin started his education from Lawson Elementary School in Chicago. He enjoyed studying. It gave him satisfaction as his hunger for knowledge was fulfilled. Here he came across two teachers who became a great inspiration to him in life.

First, Mr Kinney — a perfectionist, who taught home grooming and wood shop classes. Although he was demanding, Kenny was very kind beneath a tough veneer. He would push Martin to utilize his complete potential. Instead of retaliating against this pressure, Martin acknowledged it and pursued perfection. As Martin was immensely interested in gaining knowledge, books became his obsession.

Martin went on to pursue his further studies at Illinois Institute of Technology, Chicago. He decided to become a physicist, and almost became one. But the subject Chemistry made him change his mind. He realized, that to be a physicist, one had to opt for Chemistry compulsorily. When Martin attended his first chemistry practical, he could relate it to cooking.

This does not surprise me as chemistry is all about getting the combinations and experiments right! I mean, have you been to a chemistry lab? It stinks! Try and imagine smelling rotten eggs with jasmine in a pool of mixed perfumes. A chemistry lab is a hub for such odd odours. Now, since childhood Martin had avoided learning how to cook and was least interested in it.

He probably saw the beakers as vessels and burners as stove. Hence obviously, Martin was a total disaster in the chemistry lab. He realized it was impossible to be a physicist unless he got better at chemistry. Martin reconsidered his choice. He switched from becoming a physicist to an engineer. He obtained the degree in and continued his studies for a post graduate degree from the same university.

A was an active participant in the Korean conflict. The conflict was a war between North Korea that was occupied by communism and South Korea which was supported by capitalist countries. Martin served in the U. Navy Destroyer during the Korean War and destroyed railway tracks. He received a presidential unit citation medal from President Singhman Rhee of Korea for his services.

After that, Martin went to a submarine school in New London. Tang sc. During this time, he picked up scuba diving, one of his many athletic pastimes. He cherished his days of service, but over a period of time the feeling to settle down soon began to grow within him. So, Martin left the navy as a Submarine Officer after three and a half years of service.

He would start at 9a. As a bell rang at 5p. This orderly progression did not appeal to Martin. During his time at Bell system, Martin once noticed an event that filled him with abhorrence towards the company. He saw a new superintendent come in and because he was a level lower than the guy who had previously occupied the office, the head had the carpet removed.

Martin realized that he always had a few leftover parts and still the machines would work just as well.

It still did not click to him that he had the potential to improve and innovate. A Teletype machine is a character printer connected to a telegraph that operates like a typewriter. While working at Teletype Corp, Martin got an offer from Motorola. At that time, Motorola dealt in Radio-related products. And guess what! Martin used to study alongside.

But this did not hinder his devotion to his work. Within two years, Martin was awarded his first patent for a selective signalling device. He achieved his M. The following year, Martin got a patent for the first automatic push-button radio telephone for rural U. In , Martin was instrumental in changing the CMOS sheets that were previously limited to the information technology.

CMOS technology is also used for several analogue circuits such as image sensors CMOS sensor , data converters, and highly integrated transceivers for many types of communication. Martin also helped to fix the defects in the crystal which Motorola made for radio. This prompted the company to mass-produce the first quartz crystals. He also received a patent for introducing radio-controlled traffic light system.

The guy was brilliant and had colossal energy. Mitchell noticed him. John was quick to learn that Martin was gifted and had great potential in overcoming hurdles. He assigned Martin to the division that was working on the first portable hand-held police radios, which were introduced in Chicago in Later, Martin also played a major role in the establishment of the high-capacity paging market.

He introduced the Pageboy II, the first of its kind, high-capacity, nationwide radio. He was also a part of the team that made supporting terminals for city wide high-capacity paging. During this time, he met Homer Harris in Los Angeles. John grew confident with his observations about Martin. He was promoted and made a Division Manager. The FCC is a government body that regulates interstate and international communications by radio, television, wire, satellite and cable.

For this, they asked for thirty megahertz of spectrum. Since each city only had thirty channels, it meant a monopoly. Their model required immense charge, which was provided by the car battery, hence bounding it and the user to the car. Motorola had learnt from their land-mobile business experiences that people are fundamentally mobile.
